Hopefully an easy question.

I have a 3910 and a new service on the server requires the use of port 443, but before I open this port and cause problems for VPN, can someone tell me if Draytek use port 443 for Ipsec traffic? The internet suggests not, but I do not want to cause myself untold pain by making a change to then have to sort the mess  

Thanks in advance

 

Hi Iain ,

I'm pretty sure IPsec on the DrayTek routers use 'ESP IP50' which is portless...

Otherwise it's UDP 500 or UDP 4500.

Excellent, thank you...
